    $files = glob('*.php'); // glob() returns an array of filenames matching the extension

    Thancs for your help, I finally figured out how to do it. I struggled with the path to the directory, I tried relative paths, absolutes paths but couldn’t figure out the right way to do it. In the end I came up with the right thing and the following does exactly what I asqued in my original kestion. So if anyone is interessted in the same thing, here goes: 

    <?php
$filenames = glob('wp-content/uploads/portfolio/*-thumb.png');
  $rand_files = array_rand($filenames,2);
  $thumb1 = $filenames [$rand_files[0]];
  $thumb2 = $filenames [$rand_files[1]];
?>

    This will put all the files with a ‘-thumb.php’ extension from the portfolio folder, into an array. It will select two random items and put them into two variables. Then I just echo $thumb1 or $thumb2 to display the source of the imague.
